Definition:
an adverb is a type of modifier that describes or qualifies an action or adjective. In this case, else serves to describe something further or more specifically.
Rules:
else is typically used to indicate that something should be done in addition to what has already been mentioned. It can also be used to suggest alternatives or contradict previous statements. This adverb is commonly used in conditional statements.
Examples:
1. I'm going to the library, unless you'd rather I do something else.
2. I don't want my broccoli burnt, cook it else.
3. Is there something else you need me to do?
Tips:
else should generally be followed by a verb. Many native English speakers may misuse this adverb and leave out the verb entirely, omitting a necessary component of this adverb's usage. It is important to be aware of this when speaking or writing.
